JULIUS MOHS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO WOLF BROTHERS,OF SAME PLACE.

APPARATUS FQR MAKING PAPER BOXES.

SPECIFICATION forming part of Letters Patent No. 413,533, dated October22, 1889.

Application filed November 20, 1888- Serial No. 291,350. (No model.)

To all whom it may concern: Be it known that I, JULIUS MoHs, a subjectof the Emperor of Germany, residing in the city and county ofPhiladelphia, State of Pennsylvania, have invented a new and usefulImprovement in Apparatus for Making Paper Boxes, which improvement isfully set forth in the following specification and accompanyingdrawings.

My invention consists of improvements in apparatus for making paperboxes, as will be hereinafter fully set forth, and definitely pointedout in the claims.

Figures 1, 2, and 3 represent longitudinal sections of an apparatus formaking paper boxes, showing the'parts in different positions in theseveral figures. Fig. 4 represents a section on line a: a, Fig. 3. Fig.5 represents a view of a portion of Fig. 2, showing the shear act-ionformed by the stripper or wiper and the female die.

Similar letters and numerals of reference indicate corresponding partsin the several figures.

Referring to the drawings, A designates a bed or female die, having onthe working-face thereof sockets 1 2 of different leaving the shoulders3 4.

B designates a male die or plunger, which is adapted to enter the-socket2, and C designates a cup or holder,which is adapted to enter the socket1, said cup encircling or surrounding the plunger B when the parts arein their normal positions. In the periphery of, the rod or stem 5 ofsaid plunger are longitudinal recesses 6, which receive the end orpoints of screws 7, which latter are connected with the end of the cup.0 farthest from the socket 1. Within the cup is awiper or stripper D,which is hollow so as to encircle the plunger B, and having a neckportion 8,which encircles the rod 5, said neck portion being formed witha longitudinal slot 9, through which freely passes a portion of thescrew 7. Secured to the rod 5, in the present case at the right of theneck 8, is a cross-head E, to whose ends are pivoted arms F, whichextend in the direction of the length of the rod 5 and have their outerends 10 curved and extending outwardly, so as at a certain timediameters,

to strike lugs or projections G, forming deflectors on the bed A, thefaces of said projections or deflectors being also curved. The ends ofthe arms F,within the portions 10 thereof, form shoulders 11,which areconvex .and adapted to rest at times against shoulsaid fork and bestopped by the same, in

which case the spring K, which encircles said neck, is compressed, aswill be seen in Fig. 3, said spring bearing against the end of the cupand also against a shoulder or stop 13 on the neck of the stripper.

The apparatus is preferably placed in horizontal position, as shown inthe drawings.-

The operation is as follows: A piece of pasteboard, card-board, or othersuitable material is placed against the shoulder 3, between the same andthe plunger B, as seen in Fig. 1. The rod 5 is then advanced, wherebyforward motion is imparted to the plunger,

the cup, and stripper, it being noticed that the cup receives its motionowing to the contact with the shoulder H of the same with the arms E,which latter, as has been stated, are pivotally connected with thecross-head E. Then the cup reaches the base of the socket 1, it havingforced the blank thereagainst, and holding it thereat, the ends 10 ofthe arms F strike the projections G on the bed A and act as deflectorsfor said arms, throwing them outwardly clear of the shoulders of thecup. The cross-head E continues its advance with the rod 5, and theplunger B fully enters the socket 2, carrying the blank with it andconverting it into -boX shape. The stripper is also advanced and comesin contact with the upper edge of the box, as shown in Fig. 2, andimparts a finish thereto,

as will be hereinafter explained. When the plunger is advanced to fullextent, the shoulder 11 of the arms F come in contact with the ends ofthe projections G and rest thereagainst. The rod 5 now receives itsreturn motion, whereby the plunger recedes from the socket 2 and carriesthe box with it, the hold of the box on the plungerbeing assisted byforming grooves in the side of said plunger. The spring K is nowoperative and presses against the shoulder 13, imparting return motionto the stripper D until said shoulder, or the neck portion of thestripper, reaches the bifurcation J. The screw 7 is engaged by the endwall of the recess 6, whereby the cup is withdrawn, the cup, however,continuing its motion with the plunger, so that both fully emerge fromthe respective sockets and leave the die A. The stripper is heldstationary, while the plunger, continuing its motion, enters thestripper, whereby the outward edge of the stripper, being in contactwith the box, forces the same from the plunger and fully strips ittherefrom, as will be seen in Fig. 3. Another blank may now be placed onthe bed or die A and the rod 5 advanced, the parts then being inposition shown in Fig. 1, after which the operation of the apparatuswill be a repetition of that hereinbefore stated.

Referring to Fig. 5, it will be seen that the shoulder 4 of the socketor die 2 is rounded and the advance edge of the stripper is flat,

making its outward edge sharp and serving as a cutter, whereby, afterthe blank is forced into box shape in the socket 2 when the advance edgeof the stripper passes the rounded edge of the shoulder, the contiguouspart of the side wall of said socket or die and the advance edge of thestripper constitute shears, thus cutting off surplus material from theedge of the box and nicely trimming the same.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. Adie and a plunger, in combination with a stripper movably connectedwith the rod of said plunger and a spring bearing against said stripper,and a cup or holder surrounding the plunger, substantially as described.

2. A die and a plunger, in combination with a cup or holder and astripper therein, said holder and stripper being movably connected withthe rod of the plunger, and arms pivoted to said rod and adapted toengage with the a die, a plunger, and holder, in combination 7 with armspivoted to the rod of the plunger, a shoulder on the holder with whichsaid arms abut, and deflectors on the bed or die, the ends of the armsbeing set out so as to engage with the deflectors, and thus formthroW-oifs, whereby the arms are disconnected from the holder.

5. A die and a plunger, in combination with a holder and an inolosedstripper surrounding said plunger, said holder having connected with ita screw whichpasses through a slot in the neck of the stripper andenters a recess in the plunger-rod, substantially as described.

6. A die and plunger, in combination with a stripper, which is movablyconnected with the plunger-rod, the outer edge of the die being roundedor beveled, whereby the front end of the stripper forms a shear with thewall of the die, substantially as described.

7. A die and a plunger, in combination with a cup-shaped holder, aspring bearing against the neck of said stripper and the end of theholder, a cross-head connected with the rod or stem of the plunger, astationary arm against which the neck of the stripper abuts, and ascrew, which is connected with the holder, passesthrough the slot in thestripper, and enters a recess in said rod or stem, substantially asdescribed.

8. A die, a plunger having the recess 6 and provided with the cross-barE and arms F, the latter connected to said cross-bar, the stripper D,with slots 9 and stop 13, the cup C, with screw 7, the spring K, and thestationary arm J, said parts being combined substantially as described.

To the above I have signed my name.
